Hanwha Q CELLS half-cell, six-busbar module wins Intersolar PV award

Hanwha Q CELLS has secured another achievement in the Intersolar Award 2018 Photovoltaics category with its Q.PEAK DUO-G5 solar module. Having triumphed in 2017 with Hanwha Q CELLS’ innovative Q.PEAK RSF L-G4.2 steel frame module, the company saw the 120 half-cell, six busbar monocrystalline module selected by the independent Intersolar Award Jury as one of the most innovative out of 10 entries shortlisted from 51 total applications.

“We are once again extremely pleased with the decision of the Intersolar Award Jury. Our Q.PEAK DUO-G5 module combines a number of innovations on different levels with our high performance cell technology Q.ANTUM DUO,” said Daniel JW Jeong, Hanwha global CTO. “The durability, power increase and improved shading response performance of the module ensure that the module stands out in an increasingly competitive field. The Q.PEAK DUO-G5 solar module series is now available for customers in Europe and various international markets.”

Q.PEAK DUO-G5 is a monocrystalline 120 half-cell solar module. Based on Q.ANTUM DUO Technology, it combines the following innovations to reach the lowest LCOE:

Six busbar design
– 2×6-in. half cells with six busbars in parallel produce up to 3.5% power gain versus a typical full cell, four busbar module
– Six busbars in combination with half-cell technology help to lower resistive losses

Round wire interconnection
– Use of round wires instead of flat ribbons for cell interconnection reduces the effective shading on the solar cells significantly
– Benefits result in a power gain of an additional 2.0%

Improved performance and durability of half cells
– Cell interconnection with independent upper and lower module halves connected in parallel ensures an improved shading response, resulting in higher yields when the module is partially shaded
– Half-cut cells are subjected to vastly reduced mechanical stress, resulting in fewer cracks
– Halving the cell also halves the current, which lowers resistive losses in each cell and results in a 3.0% power gain against typical full cells’ interconnection
